IMPROVEMENT IN DEVICES FOR DRYING AND CONDITI ONING LEAF-TOBACCO.

Specification forming part of Letters Patent No. 196,746, dated November6, 1877; application filed August 9,1877.

To all whom it may concern:

Be it known that I,'ROBERT DUNLoP, of the city of Louisville, in thecounty of J eiferson and State of Kentucky, have invented a certain newand useful Improvement in a Device for Drying and ConditioningLeaf-Tobaceo; and I do hereby declare that the fol-- tobacco, and alsoto produce the required moi sture to put it in proper conditionpreparatory to the further process of its manufacture; consistin g,first, in -a small cylindrical furnace with a drum or water-tank overit, in connection with a series of pipes, one end of which connects withthe water-drmn near the bottom,

while a part of one pipe is formed into loopshorizontally withtheremainder, extending beyond the loop, and made to enter, theside ofthe furnace above the fire, where it is again formed into several spiralcoils within the chamber, after which the endpasses out at the side,turned up, and is made to enter the end of the drum above, which drum isalso further provided with a discharge-pipe across the end of thewater-pans, with branches .at the side over each. pan, arrangedwithfperforated strainers on the ends, by which meanssufiicient spray'isproduced to moisten the atmosphere when necessary to put the tobacco inproper condition for further use.

In the annexeddrawing, A represents the furnace, which may be made inany suitable form.- I is the fire-door, and K is the coil of pipe withinthe chamber, the object of which is to increase the heating-surface, andthereby heat the water more quickly. J is the flueopening, and B is thewater drum or tank over the furnace. G is the supply-opening, and D isthe vent-pipe, to which a safety-valve may be'attached, if required. Nis the main water-pipe, one end of which connects with the rear end ofthe water-drum .near the bottom. A part of this pipe is formed into theloops F ina horizontal manner, and may consist of any required. numberto produce suflicient heat to dry the tobacco, while the same pipeextends beyond the loops and enters the the endof the water-drum B,thereby forming a free, unobstructed passage for the water from, thedrum downintothe coils below, ,where it is heated by fire, which causesaconstant circulation through the pipe coils and. drum; R is-thestop-cock for regulating the flow of water, and L is the discharge-pipenamed branches, ing spray to moisten or eondltlon the tobaccowhen'reqnired.

discharged from thestrainers, which may increased to any j-n'umberrequired.

. Havingthus fully described the nature and object of thisiny-invention, what I claim as new,and desire to secure by LettersPatent, in a device for conditioning leaf-tobacco, is-

lhe discharge-strainers H H, by which spray is produced, in combinationwith the pipe L, drum '13, and pipe N, with its loops F, coils .K,furnace ,A, and pans G G, as above described, arranged, constructed, andoperated substantially as and for the purpose hereinbefore set forth.
